Cascaded Encryption Through Recursive Carry Addition and Key Rotation (CRCAKR) of a Session Key

The technique considers a message as binary string on which a cascaded recursive carry addition and key rotation (CRCAKR) is applied. This technique uses binary addition method. It is a kind of block cipher and symmetric in nature hence, decoding is done following the same procedure. A comparison of the proposed technique with existing RSA and Triple DES has also been done in terms of frequency distribution and homogeneity of source and encrypted files.
